DC-DC3 ON Slot select
000 = Do not enable
001 = Enable in Timeslot 1
010 = Enable in Timeslot 2
011 = Enable in Timeslot 3
100 = Enable in Timeslot 4
101 = Enable in Timeslot 5
110 = Controlled by Hardware Enable 1

DC-DC3 ON Operating Mode
00 = Forced Continuous Conduction Mode
01 = Continuous / Discontinuous Conduction with
Pulse-Skipping
10 = LDO Mode
11 = Hysteretic Mode
DC-DC3 ON Voltage select
DC3_ON_VSEL[6:0] selects the DC-DC3 output
voltage from 0.85V to 3.4V in 25mV steps.
DC3_ON_VSEL[6:2] also exist in DBE/OTP memory,
controlling the voltage in 100mV steps.
DC3_ON_VSEL[6:0] is coded as follows:
00h = 0.85V
01h = 0.875V
…
65h = 3.375V
66h to 7Fh = 3.4V
DC3 ON Voltage select
DC3_ON_VSEL[6:0] selects the DC3 output voltage
from 0.85V to 3.4V in 25mV steps.
See DC3_ON_VSEL[6:2] for definition.
DC-DC3 SLEEP Slot select
000 = SLEEP voltage / operating mode transition in
Timeslot 5
001 = Disable in Timeslot 5
010 = Disable in Timeslot 4
011 = Disable in Timeslot 3
100 = Disable in Timeslot 2
101 = Disable in Timeslot 1
110 = SLEEP voltage / operating mode transition in
Timeslot 3
111 = SLEEP voltage / operating mode transition in
Timeslot 1
If DC-DC3 is assigned to a Hardware Enable Input,
then codes 001-101 select in which timeslot the
converter enters its SLEEP condition.
